FIELD OF THE INVENTION

The present invention provides compounds that are inhibitors of voltage-gated sodium channels (Nav), in particular Nav 1.7, and are useful for the treatment of diseases treatable by inhibition of sodium channels such as pain disorders. Also provided are pharmaceutical compositions containing compounds of the present invention.

BACKGROUND OF THE INVENTION

A 2011 report of the institute of medicine estimates that 100 million adults in the US, roughly 30 of the population, suffer from chronic pain (C & E News, Bethany Halford, “Changing the Channel”, published Mar. 24, 2014). Chronic pain by definition involves abnormal electrical spiking of neurons in the pain pathways: peripheral sensory neurons, spinal cord neurons, neurons in the pain matrix of the brain (e.g., somatosensory cortex, insular cortex, anterior cingular cortex), and/or neurons in brainstem. Although firing of these neurons is modulated and governed by many different receptors, enzymes, and growth factors, in most neurons the fast upstroke of the electrical spike is produced by entry of sodium ions through voltage-gated sodium channels (Hille B, Ion Channels of Excitable Membranes. Sinauer Associates, Inc.: Sunderland Mass., 3^(rd) Ed. 2001). There are nine different isoforms of voltage-gated sodium channel (Nav 1.1-Nav 1.9), and they have distinct expression patterns in tissues including neurons and cardiac and skeletal muscle (Goldin, A. L, “Resurgence of sodium channel research,” Ann Rev Physiol 63:871-894, 2001; Wood, J. N. and, Boorman, J. “Voltage-gated sodium channel blockers; target validation and therapeutic potential” Curr. Top Med. Chem. 5:529-537, 2005).

Nav1.1 and Nav1.2 are highly expressed in the brain (Raymond, C. K., et al., J. Biol. Chem. (2004) 279 (44):46234-41) and are vital to normal brain function. Some loss of function due to Nav 1.1 mutations in humans, have resulted in epilepsy, presumably as these channels are expressed in inhibitory neurons (Yu, F. H., et al., Nat. Neuroscience (2006), 9 (9) 1142-1149). Nav1.1 is also expressed in the peripheral nervous system and inhibition of Nav1.1 in the periphery may provide relief of pain. Hence, while inhibiting Nav1.1 may provide use fro treating pain, it may also be undesirable possibly leading to anxiety and over excitability. Nav1.3 is expressed primarily in the fetal central nervous system, and expression was found to be upregulated after nerve injury in rats (Hains, B. D., et al., J. Neuroscience (2030) 23(26):8881-8892). Nav1.4 is epressed primarily in skeletal muscle. Mutations of the gene and its' product have significant impact on muscle function, including paralysis (Tamaoka A., Internal Medicine (2003), (9):769-770). Nav1.5 is expressed mainly in cardiac myocytes, including atria, ventricles, the sino-atrial node, atrio-ventircular node and cardiac Purkinje fibers. The rapid upstroke of the cardiac action potential and the rapid impulse condution through cardiac tissue is due to the opening of the Nav1.5 channel. Mutations of the Nav1.5 channel have resulted in arrhythmic syndromes, including QTc prolongation, Brugada syndrome (BS), sudden-unexpected nocturnal death sybdrome (SUNDS) and sudden infant death syndrome (SIDS) (Liu, H., et al., Am. J. Pharmacogenomics (2003), 3(3):173-179). Nav1.6 is widely distributed voltage-gated sodium channel expressed throughout the central and peripheral nervous system. Nav1.8 is expressed primarily in sensory ganglia of the peripheral nervous system, such as the dorsal root ganglia. There are no identified Nav1.8 mutations that produce varied pain responses in humans. Nav1.8 differs from most neuronal Nay isotypes in that it is insensitive to inhibition by tetrodotoxin. Nav1.9, similar to nav1.8, is also a tetrodotoxin insensitive sodium cahnngel expressedprimarily in dorsal root ganglia neurons (Dib-Hajj, S. D., et al., Proc. Natl. Acad. Sci. USA (1998), 95(15):8963-8968).

Recent evidence from several independent genetic studies has shown that the tetrodotoxin-sensitive voltage-gated sodium ion channel Nav 1.7 (SCN9A) is required to sense pain. Rare genetic forms of severe chronic pain, Primary Erythromelalgia and Paroxysmal Extreme Pain Disorder, result from mutations that increase the activity of Nav 1.7 (Fertleman C. R., Baker M. D., Parker K. A., Moffatt S., et al., “SCN9A mutations in paroxysmal extreme pain disorder: allelic variants underlie distinct channel defects and phenotypes,” Neuron 52:767-774, 2006; Yang Y., Wang Y., Li S, et al., “Mutations in SCN9A, encoding a sodium channel alpha subunit, in patients with primary erythermalgia,” J. Med. Genet. 41:171-174, 2004; Drenth J. P. H., to Morsche R. H. M., Guillet G., Taieb A., et al., “SCN9A mutations define primary erythermalgia as a neuropathic disorder of voltage gated sodium channels,” J Invest Dermatol 124:1333-1338). Conversely, two separate clinical studies have determined that the root cause of the genetic disorder Congenital Indifference to Pain (CIP) is a loss of function of Nav 1.7 via mutations that truncate the protein and destroy function (Cox J. J., Reimann F, Nicholas A. K., et al. “An SCN9A channelopathy causes congenital inability to experience pain,” Nature 444:894-898, 2006; Goldberg Y. P., MacFarlane J., MacDonald M. L., Thompson J., et al. “Loss-of-function mutations in the Nav1.7 gene underlie congenital indifference to pain in multiple human populations,” Clin Genet. 71:311-319, 2007). The disorder is inherited in Mendelian recessive manner with 100% penetrance. The phenotype associated with CIP is extreme: affected individuals are reported to have experienced painless burns, childbirth, appendicitis, and bone fractures, as well as to have insensitivity to clinical measures of pain such as pinprick or tendon pressure. Yet sensory, motor, autonomic, and other measured functions are normal, with the only reported abnormality being anosmia (inability to smell). These studies indicate that among the many possible targets in the pain pathway, Nav 1.7 governs one or more control points critical for pain perception.

Nonselective sodium channel inhibitors such as lidocaine, mexiletine, and carbamazepine show clinical efficacy in chronic pain, including neuropathic pain, but they are limited in dose and in use, likely due to effects on sodium channels outside the pain pathway. Lidocaine is a local anesthetic doctors use for minor surgery. So is the dentists office staple novocaine. But these compounds don't distinguish between the various sodium channel subtypes, making them unsuitable for use as systemic pain killers. “If you give a drug that blocks Nav1.7 but also blocks Nav1.5, the patient will die of heart failure,” says Glenn F. King, a professor at Australia's University of Queensland who studies venoms that block ion channels. “It will be a completely painless death, but the patient will die nonetheless.” Thus, selectivity for Nav1.7 is desired, particularly over Nav1.5. Researchers have tailored their efforts to find a molecule that inhibitors or block the activity of only Nav1.7. To compound this problem, the identity, every location, every function and/or the tertiary structures of each subtype of voltage gated sodium channel proteins are not known or completely understood.

Consequently, a number of researchers are attempting to identify small molecule inhibitors of Nav1.7. For example, Chafeev et al disclose spiro-oxindole compound for the treatment and/or prevention of sodium channel-mediated diseases, such as pain, in U.S. Pat. No. 8,101,647. Thus, there is a need to identify Nav1.7 inhibitors selective over at least Nav1.5 to treat pain. The present invention provides compounds that are inhibitors of Nav 1.7.

Typical substitutents include: halogen, C₁₋₈alkyl, hydroxyl, C₁₋₈alkoxy, NR^(x)R^(x), nitro, cyano, halo or perhaloC₁₋₈alkyl, C₂₋₈alkenyl, C₂₋₈alkynyl, SR^(x), —S(═O)₂R^(x), C(═O)OR^(x), C(═O)R^(x), wherein each R^(x) is independently hydrogen or C₁-C₈ alkyl. It is noted that when the substituent is NIVR^(x), the R^(x) groups may be joined together with the nitrogen atom to form a ring.

The term “oxo”, when used as a substituent, means the ═O group, which is typically attached to a carbon atom.

A group or atom that replaces a hydrogen atom is also called a substituent. Any particular molecule or group can have one or more substituent depending on the number of hydrogen atoms that can be replaced.

The symbol “—” represents a covalent bond and can also be used in a radical group to indicate the point of attachment to another group. In chemical structures, the symbol is commonly used to represent a methyl group in a molecule.

The term “therapeutically effective amount” means an amount of a compound that ameliorates, attenuates or eliminates one or more symptoms of a particular disease or condition, or prevents or delays the onset of one of more symptoms of a particular disease or condition.

The term “patient” means animals, such as dogs, cats, cows, horses, sheep and humans. Particular patients are mammals. The term patient includes males and females.

The term “pharmaceutically acceptable” means that the referenced substance, such as a compound of the present invention or a formulation containing a compound of the present invention, or a particular excipent, are suitable for administration to a patient.

The terms “treating”, “treat” or “treatment” and the like include preventative (e.g., prophylactic) and palliative treatment.

The term “patient in need thereof” means a patient who has or is at risk of having a disease and/or condition that can be treated by inhibition of Nav 1.7, such as chronic pain.

The term “excipient” means any pharmaceutically acceptable additive, carrier, diluent, adjuvant, or other ingredient, other than the active pharmaceutical ingredient (API), which is typically included for formulation and/or administration to a patient.

The compounds of the present invention are administered to a patient in a therapeutically effective amount. The compounds can be administered alone or as part of a pharmaceutically acceptable composition or formulation. In addition, the compounds or compositions can be administered all at once, as for example, by a bolus injection, multiple times, such as by a series of tablets, or delivered substantially uniformly over a period of time, as for example, using transdermal delivery. It is also noted that the dose of the compound can be varied over time.

In addition, the compounds of the present invention can be administered alone, in combination with other compounds of the present invention, or with other pharmaceutically active compounds. The other pharmaceutically active compounds can be intended to treat the same disease or condition as the compounds of the present invention or a different disease or condition. If the patient is to receive or is receiving multiple pharmaceutically active compounds, the compounds can be administered simultaneously, or sequentially. For example, in the case of tablets, the active compounds may be found in one tablet or in separate tablets, which can be administered at once or sequentially in any order. In addition, it should be recognized that the compositions may be different forms. For example, one or more compound may be delivered by a tablet, while another is administered by injection or orally as a syrup. All combinations, delivery methods and administration sequences are contemplated.

The compounds of the present invention may be used in the manufacture of a medicament for the treatment of a disease and/or condition mediated by Nav 1.7, such as pain, chronic cough or itch.

Pain is typically divided into primary types: chronic and acute pain based on the duration of the pain. Typically, chronic pain lasts for longer than 3 months. Examples of chronic pain include pain associated with rheumatoid arthritis, osteoarthritis, lumbosacral radiculopathy or cancer. Chronic pain also includes idiopathic pain, which is pain that has no identified cause. An example of idiopathic pain is fibromyalgia.

Another type of pain is nociceptive pain. Nociceptive pain is caused by stimulation of peripheral nerve fibers that respond to highly noxious events such as thermal, mechanical or chemical stimuli.

Still another type of pain is neuropathic pain. Neuropathic pain is pain that is caused by damage or disease affecting a part of the nervous system. Phantom limb pain is a type of neuropathic pain. In phantom limb pain, the body detects pain from a part of a body that no longer exists. For example, a person who has had a leg amputated may feel leg pain even though the leg no longer exists.

In one embodiment of the methods of treatment provided by the present invention using the compounds of Formula I, or pharmaceutically acceptable salts thereof, the disease is chronic pain. In another aspect, the chronic pain is associated with, but are not limited to, post-herpetic neuralgia (shingles), rheumatoid arthritis, osteoarthritis, diabetic neuropathy, complex regional pain syndrome (CRPS), cancer or chemotherapy-induced pain, chronic back pain, phantom limb pain, trigeminal neuralgia, HIV-induced neuropathy, cluster headache disorders, and migraine, primary erythromelalgia, and paroxysmal extreme pain disorder.

Other indications for Nav 1.7 inhibitors include, but are not limited to, depression (Morinville et al., J Comp Neurol., 504:680-689 (2007)), bipolar and other CNS disorders (Ettinger and Argoff, Neurotherapeutics, 4:75-83 (2007)), epilepsy: ibid., and Gonzalez, Termin, Wilson, Methods and Principles in Medicinal Chemistry, 29:168-192 (2006)), multiple sclerosis (Waxman, Nature Neurosci. 7:932-941 (2006)), Parkinson's (Do and Bean, Neuron 39:109-120 (2003); Puopolo et al., J. Neurosci. 27:645-656 (2007)), restless legs syndrome, ataxia, tremor, muscle weakness, dystonia, tetanus (Hamann M., et. al., Exp. Neurol. 184(2):830-838, 2003), anxiety, depression: McKinney B. C, et. al., Genes Brain Behav. 7(6):629-638, 2008), learning and memory, cognition (Woodruff-Pak D. S., et. al., Behav. Neurosci. 120(2):229-240, 2006), cardiac arrhythmia and fibrillation, contractility, congestive heart failure, sick sinus syndrome (Haufe V., et. al., J. Mol. Cell. Cardiol. 42(3):469-477, 2007), schizophrenia, neuroprotection after stroke, drug and alcohol abuse (Johannessen L. C., CNS Drugs 22(1)27-47, 2008), Alzheimer's (Kim D. Y., et. al., Nat. Cell. Biol. 9(7):755-764, 2007), and cancer (Gillet L., et. al., J Biol Chem 2009, Jan. 28 (epub)).

Another aspect of the invention relates to a method of treating acute and/or chronic inflammatory and neuropathic pain, dental pain, general headache, migraine, cluster headache, mixed-vascular and non-vascular syndromes, tension headache, general inflammation, arthritis, rheumatic diseases, rheumatoid arthritis, osteoarthritis, inflammatory bowel disorders, inflammatory eye disorders, inflammatory or unstable bladder disorders, psoriasis, skin complaints with inflammatory components, chronic inflammatory conditions, inflammatory pain and associated hyperalgesia and allodynia, neuropathic pain and associated hyperalgesia and allodynia, diabetic neuropathy pain, causalgia, sympathetically maintained pain, deafferentation syndromes, asthma, epithelial tissue damage or dysfunction, herpes simplex, disturbances of visceral motility at respiratory, genitourinary, gastrointestinal or vascular regions, wounds, burns, allergic skin reactions, pruritus, vitiligo, general gastrointestinal disorders, gastric ulceration, duodenal ulcers, diarrhea, gastric lesions induced by necrotising agents, hair growth, vasomotor or allergic rhinitis, bronchial disorders or bladder disorders, comprising the step of administering a compound according to the present invention. A preferred type of pain to be treated is chronic neuropathic pain. Another preferred type of pain to be treated is chronic inflammatory pain.

In another aspect of the invention, the compounds of the present invention can be used in combination with other compounds that are used to treat pain. Examples of such other compounds include, but are not limited to aspirin, celecoxib, hydrocodone, oxycodone, codeine, fentanyl, ibuprofen, ketoprofen, naproxen, acetaminophen, gabapentin and pregabalin. Examples of classes of medicines that contain compounds that can be used in combination with the compounds of the present invention include non-steroidal anti-inflammatory compounds (NSAIDS), steroidal compounds, cycloxogenase inhibitors and opiod analgesics.

The compounds of the present invention may also be used to treat diabetes, obesity and/or to facilitate weight loss.

The compounds of the present invention may be used in combination with other pharmaceutically active compounds. It is noted that the term “pharmaceutically active compounds” can include biologics, such as proteins, antibodies and peptibodies.

Since one aspect of the present invention contemplates the treatment of the disease/conditions with a combination of pharmaceutically active compounds that may be administered separately, the invention further relates to combining separate pharmaceutical compositions in kit form. The kit comprises two separate pharmaceutical compositions: a compound of the present invention, and a second pharmaceutical compound. The kit comprises a container for containing the separate compositions such as a divided bottle or a divided foil packet. Additional examples of containers include syringes, boxes and bags. Typically, the kit comprises directions for the use of the separate components. The kit form is particularly advantageous when the separate components are preferably administered in different dosage forms (e.g., oral and parenteral), are administered at different dosage intervals, or when titration of the individual components of the combination is desired by the prescribing physician or veterinarian.

An example of such a kit is a so-called blister pack. Blister packs are well known in the packaging industry and are being widely used for the packaging of pharmaceutical unit dosage forms (tablets, capsules, and the like). Blister packs generally consist of a sheet of relatively stiff material covered with a foil of a preferably transparent plastic material. During the packaging process recesses are formed in the plastic foil. The recesses have the size and shape of the tablets or capsules to be packed. Next, the tablets or capsules are placed in the recesses and the sheet of relatively stiff material is sealed against the plastic foil at the face of the foil which is opposite from the direction in which the recesses were formed. As a result, the tablets or capsules are sealed in the recesses between the plastic foil and the sheet. Preferably the strength of the sheet is such that the tablets or capsules can be removed from the blister pack by manually applying pressure on the recesses whereby an opening is formed in the sheet at the place of the recess. The tablet or capsule can then be removed by said opening.

It may be desirable to provide a memory aid on the kit, e.g., in the form of numbers next to the tablets or capsules whereby the numbers correspond with the days of the regimen which the tablets or capsules so specified should be ingested. Another example of such a memory aid is a calendar printed on the card, e.g., as follows “First Week, Monday, Tuesday, . . . etc . . . Second Week, Monday, Tuesday, . . . ” etc. Other variations of memory aids will be readily apparent. A “daily dose” can be a single tablet or capsule or several pills or capsules to be taken on a given day. Also, a daily dose of a compound of the present invention can consist of one tablet or capsule, while a daily dose of the second compound can consist of several tablets or capsules and vice versa. The memory aid should reflect this and aid in correct administration of the active agents.

In another specific embodiment of the invention, a dispenser designed to dispense the daily doses one at a time in the order of their intended use is provided. Preferably, the dispenser is equipped with a memory-aid, so as to further facilitate compliance with the regimen. An example of such a memory-aid is a mechanical counter which indicates the number of daily doses that has been dispensed. Another example of such a memory-aid is a battery-powered micro-chip memory coupled with a liquid crystal readout, or audible reminder signal which, for example, reads out the date that the last daily dose has been taken and/or reminds one when the next dose is to be taken.

The compounds of the present invention and other pharmaceutically active compounds, if desired, can be administered to a patient either orally, rectally, parenterally, (for example, intravenously, intramuscularly, or subcutaneously) intracisternally, intravaginally, intraperitoneally, intravesically, locally (for example, powders, ointments or drops), or as a buccal or nasal spray. All methods that are used by those skilled in the art to administer a pharmaceutically active agent are contemplated.

Compositions suitable for parenteral injection may comprise physiologically acceptable sterile aqueous or nonaqueous solutions, dispersions, suspensions, or emulsions, and sterile powders for reconstitution into sterile injectable solutions or dispersions. Examples of suitable aqueous and nonaqueous carriers, diluents, solvents, or vehicles include water, ethanol, polyols (propylene glycol, polyethylene glycol, glycerol, and the like), suitable mixtures thereof, vegetable oils (such as olive oil) and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants.

These compositions may also contain adjuvants such as preserving, wetting, emulsifying, and dispersing agents. Microorganism contamination can be prevented by adding various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, and the like. It may also be desirable to include isotonic agents, for example, sugars, sodium chloride, and the like. Prolonged absorption of injectable pharmaceutical compoitions can be brought about by the use of agents delaying absorption, for example, aluminum monostearate and gelatin.

Solid dosage forms for oral administration include capsules, tablets, powders, and granules. In such solid dosage forms, the active compound is admixed with at least one inert customary excipient (or carrier) such as sodium citrate or dicalcium phosphate or (a) fillers or extenders, as for example, starches, lactose, sucrose, mannitol, and silicic acid; (b) binders, as for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidone, sucrose, and acacia; (c) humectants, as for example, glycerol; (d) disintegrating agents, as for example, agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain complex silicates, and sodium carbonate; (a) solution retarders, as for example, paraffin; (f) absorption accelerators, as for example, quaternary ammonium compounds; wetting agents, as for example, cetyl alcohol and glycerol monostearate; (h) adsorbents, as for example, kaolin and bentonite; and (i) lubricants, as for example, talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, or mixtures thereof. In the case of capsules; and tablets, the dosage forms may also comprise buffering agents.

Solid compositions of a similar type may also be used as fillers in soft and hard filled gelatin capsules using such excipients as lactose or milk sugar, as well as high molecular weight polyethylene glycols, and the like.

Solid dosage forms such as tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells, such as enteric coatings and others well known in the art. They may also contain opacifying agents, and can also be of such composition that they release the active compound or compounds in a certain part of the intestinal tract in a delayed manner. Examples of embedding compositions that can be used are polymeric substances and waxes. The active compounds can also be in micro-encapsulated form, if appropriate, with one or more of the above-mentioned excipients.

Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, solutions, suspensions, syrups, and elixirs. In addition to the active compounds, the liquid dosage form may contain inert diluents commonly used in the art, such as water or other solvents, solubilizing agents and emulsifiers, as for example, ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils, in particular, cottonseed oil, groundnut oil, corn germ oil, olive oil, castor oil, and sesame seed oil, glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, or mixtures of these substances, and the like.

Besides such inert diluents, the composition can also include adjuvants, such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents. Suspensions, in addition to the active compound, may contain suspending agents, as for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar, and tragacanth, or mixtures of these substances, and the like.

Compositions for rectal administration are preferable suppositories, which can be prepared by mixing the compounds of the present invention with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax, which are solid at ordinary room temperature, but liquid at body temperature, and therefore, melt in the rectum or vaginal cavity and, release the active component. Dosage forms for topical administration of a compound of the present invention include ointments, powders, sprays and inhalants. The active compound or fit compounds are admixed under sterile condition with a physiologically acceptable carrier, and any preservatives, buffers, or propellants that may be required. Opthalmic formulations, eye ointments, powders, and solutions are also contemplated as being within the scope of this invention.

The compounds of the present invention can be administered to a patient at dosage levels in the range of about 0.1 to about 3,000 mg per day. For a normal adult human having a body weight of about 70 kg, a dosage in the range of about 0.01 to about 100 mg per kilogram body weight is typically sufficient. The specific dosage and dosage range that can be used depends on a number of factors, including the requirements of the patient, the severity of the condition or disease being treated, and the pharmacological activity of the compound being administered. The determination of dosage ranges and optimal dosages for a particular patient is within the ordinary skill in the art.

The compounds of the present invention can be administered as pharmaceutically acceptable salts, cocrystyals, esters, amides or prodrugs. The term “salts” refers to inorganic and organic salts of compounds of the present invention. The salts can be prepared in situ during the final isolation and purification of a compound, or by separately reacting a purified compound in its free base or acid form with a suitable organic or inorganic base or acid and isolating the salt thus formed. Representative salts include the hydrobromide, hydrochloride, sulfate, bisulfate, nitrate, acetate, oxalate, palmitiate, stearate, laurate, borate, benzoate, lactate, phosphate, tosylate, citrate, maleate, fumarate, succinate, tartrate, naphthylate, mesylate, glucoheptonate, lactobionate, and laurylsulphonate salts, and the like. The salts may include cations based on the alkali and alkaline earth metals, such as sodium, lithium, potassium, calcium, magnesium, and the like, as well as non-toxic ammonium, quaternary ammonium, and amine cations including, but not limited to, ammonium, tetramethylammonium, tetraethylammonium, methylamine, dimethylamine, trimethylamine, triethylamine, ethylamine, and the like. See, for example, S. M. Berge, et al., “Pharmaceutical Salts,” J Pharm Sci, 66: 1-19 (1977).

Examples of pharmaceutically acceptable esters of the compounds of the present invention include C₁-C₈ alkyl esters. Acceptable esters also include C₅-C₇ cycloalkyl esters, as well as arylalkyl esters such as benzyl. C₁-C₄ alkyl esters are commonly used. Esters of compounds of the present invention may be prepared according to methods that are well known in the art.

Examples of pharmaceutically acceptable amides of the compounds of the present invention include amides derived from ammonia, primary C₁-C₈ alkyl amines, and secondary C₁-C₈ dialkyl amines. In the case of secondary amines, the amine may also be in the form of a 5 or 6 membered heterocycloalkyl group containing at least one nitrogen atom. Amides derived from ammonia, C₁-C₃ primary alkyl amines and C₁-C₂ dialkyl secondary amines are commonly used. Amides of the compounds of the present invention may be prepared according to methods well known to those skilled in the art.

The term “prodrug” means compounds that are transformed in vivo to yield a compound of the present invention. The transformation may occur by various mechanisms, such as through hydrolysis in blood. A discussion of the use of prodrugs is provided by T. Higuchi and W. Stella, “Pro-drugs as Novel Delivery Systems,” Vol. 14 of the A. C. S. Symposium Series, and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987.

To illustrate, if the compound of the invention contains a carboxylic acid functional group, a prodrug can comprise an ester formed by the replacement of the hydrogen atom of the acid group with a group such as (C₁-C₈ alkyl, (C₂-Cl₂)alkanoyloxymethyl, 1-(alkanoyloxy)ethyl having from 4 to 9 carbon atoms, 1-methyl-1-(alkanoyloxy)ethyl having from 5 to 10 carbon atoms, alkoxycarbonyloxymethyl having from 3 to 6 carbon atoms, 1-(alkoxycarbonyloxy)ethyl having from 4 to 7 carbon atoms, 1-methyl-1-(alkoxycarbonyloxy)ethyl having from 5 to 8 carbon atoms, N-(alkoxycarbonyl)aminomethyl having from 3 to 9 carbon atoms, 1-(N-(alkoxycarbonyl)aminomethyl having from 4 to 10 carbon atoms, 3-phthalidyl, 4-crotonolactonyl, gamma-butyrolacton-4-yl, di-N,N—(C₁-C₂)alkylamino(C₂-C₃)allyl (such as (3-dimethylaminoethyl), carbamoyl-(C₁-C₂)alkyl, N,N-di(C₁-C₂)alkylcarbamoyl-(C₁-C₂)alkyl and piperidino-, pyrrolidino- or morpholino(C₂₋₃)alkyl.

Similarly, if a compound of the present invention comprises an alcohol functional group, a prodrug can be formed by the replacement of the hydrogen atom of the alcohol group with a group such as (C₁-C₆)alkanoyloxymethyl, 1-((C₁-C₆)alkanoyloxy)ethyl, 1-methyl-1-((C₁-C₆)alkanoyloxy)ethyl, (C₁-C₆)alkoxycarbonyloxymethyl, N—(C₁-C₆)alkoxycarbonylaminomethyl, succinoyl, (C₁-C₆)alkanoyl, α-amino(C₁-C₄)alkanoyl, arylacyl and α-aminoacyl, or α-aminoacyl-α-aminoacyl, where each α-aminoacyl group is independently selected from the naturally occurring L-amino acids, P(O)(OH)₂, P(O)(O(C₁-C₆)alkyl)₂ or glycosyl (the radical resulting from the removal of a hydroxyl group of the hemiacetal form of a carbohydrate).

In addition, if a compound of the present invention comprises a sulfonamide moiety, a prodrug can be formed by replacement of the sulfonamide N(H) with a group such as —CH₂P(O)(O(C₁-C₆)alkyl)₂ or —CH₂OC(O)(C₁-C₆)alkyl.

The compounds of the present invention also include tautomeric forms of prodrugs.

The compounds of the present invention may contain asymmetric or chiral centers, and therefore, exist in different stereoisomeric forms. It is contemplated that all stereoisomeric forms of the compounds as mixtures thereof, including racemic mixtures, form part of the present invention. In addition, the present invention contemplates all geometric and positional isomers. For example, if the compound contains a double bond, both the cis and trans forms (designated as S and E, respectively), as well as mixtures, are contemplated.

Mixture of stereoisomers, such as diastereomeric mixtures, can be separated into their individual stereochemical components on the basis of their physical chemical differences by known methods such as chromatography and/or fractional crystallization. Enantiomers can can also be separated by converting the enantiomeric mixture into a diasteromeric mixture by reaction with an appropriate optically active compound (e.g., an alcohol), separating the diastereomers and converting (e.g., hydrolyzing) the individual diastereomers to the corresponding pure enantiomers. Also, some compounds may be atropisomers (e.g., substituted biaryls that are steoisomeric due to hindered rotation around a bond).

The compounds of the present invention may exist in unsolvated as well as solvated forms with pharmaceutically acceptable solvents such as water (hydrate), ethanol, and the like. The present invention contemplates and encompasses both the solvated and unsolvated forms.

It is also possible that compounds of the present invention may exist in different tautomeric forms. All tautomers of compounds of the present invention are contemplated. For example, all of the tautomeric forms of the tetrazole moiety are included in this invention. Also, for example, all keto-enol or imine-enamine forms of the compounds are included in this invention. Other examples of tautomerism are as follows:

Those skilled in the art will recognize that the compound names and structures contained herein may be based on a particular tautomer of a compound. While the name or structure for only a particular tautomer may be used, it is intended that all tautomers are encompassed by the present invention, unless stated otherwise.

It is also intended that the present invention encompass compounds that are synthesized in vitro using laboratory techniques, such as those well known to synthetic chemists; or synthesized using in vivo techniques, such as through metabolism, fermentation, digestion, and the like. It is also contemplated that the compounds of the present invention may be synthesized using a combination of in vitro and in vivo techniques.

The present invention also includes isotopically-labelled compounds, which are identical to those recited herein, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number usually found in nature. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine and chlorine, such as ²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁶O, ¹⁷O, ³¹P, ³²P, ³⁵S, ¹⁸F, and ³⁶Cl. In another aspect, the compounds of the present invention contain one or more deuterium atoms (2H) in place of one or more hydrogen atoms.

Compounds of the present invention that contain the aforementioned isotopes and/or other isotopes of other atoms are within the scope of this invention. Certain isotopically-labelled compounds of the present invention, for example those into which radioactive isotopes such as ³H and ¹⁴C are incorporated, are useful in drug and/or substrate tissue distribution assays. Tritiated, i.e., ³H, and carbon-14, i.e., ¹⁴C, isotopes are particularly preferred for their ease of preparation and detection. Further, substitution with heavier isotopes such as deuterium, i.e., ²H, can afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements and, hence, may be preferred in some circumstances. Isotopically labelled compounds of this invention can generally be prepared by substituting a readily available isotopically labelled reagent for a non-isotopically labelled reagent.

The compounds of the present invention may exist in various solid states including crystalline states and as an amorphous state. The different crystalline states, also called polymorphs, and the amorphous states of the present compounds are contemplated as part of this invention.

In synthesizing compounds of the present invention, it may be desirable to use certain leaving groups. The term “leaving groups” (“LG”) generally refer to groups that are displaceable by a nucleophile. Such leaving groups are known in the art. Examples of leaving groups include, but are not limited to, halides (e.g., I, Br, F, Cl), sulfonates (e.g., mesylate, tosylate), sulfides (e.g., SCH₃), N-hydroxsuccinimide, N-hydroxybenzotriazole, and the like. Examples of nucleophiles include, but are not limited to, amines, thiols, alcohols, Grignard reagents, anionic species (e.g., alkoxides, amides, carbanions) and the like.

All patents and other publications recited herein are hereby incorporated by reference in their entirety.

The examples presented below illustrate specific embodiments of the present invention. These examples are meant to be representative and are not intended to limit the scope of the claims in any manner.

It is noted that when a percent (%) is used with regard to a liquid, it is a percent by volume with respect to the solution. When used with a solid, it is the percent with regard to the solid composition. Materials obtained from commercial suppliers were typically used without further purification. Reactions involving air or moisture sensitive reagents were typically performed under a nitrogen or argon atmosphere. Purity was measured using high performance liquid chromatography (HPLC) system with UV detection at 254 nm and 215 nm (System A: Agilent Zorbax Eclipse XDB-C8 4.6×150 mm, 5 μm, 5 to 100% CH₃CN in H₂O with 0.1% TFA for 15 min at 1.5 mL/min; System B: Zorbax SB-C8, 4.6×75 mm, 10 to 90% CH₃CN in H₂O with 0.1% formic acid for 12 min at 1.0 mL/min) (Agilent Technologies, Santa Clara, Calif.). Silica gel chromatography was generally performed with prepacked silica gel cartidges (Biotage, Uppsala, Sweden or Teledyne-Isco, Lincoln, Nebr.). ¹H NMR spectra were recorded on a Bruker AV-400 (400 MHz) spectrometer (Bruker Corporatiori, Madison, Wis.) or a Varian (Agilent Technologies, Santa Clara, Calif.) 400 MHz spectrometer at ambient temperature. All observed protons are reported as parts per million (ppm) downfield from tetramethylsilane (TMS) or other internal reference in the appropriate solvent indicated. Data are reported as follows: chemical shift, multiplicity (s=singlet, d=doublet, t=triplet, q=quartet, br=broad, m=multiplet), coupling constants, and number of protons. Low-resolution mass spectral (MS) data were determined on an Agilent 1100 Series (Agilent Technologies, Santa Clara, Calif.) LC/MS with UV detection at 254 nm and 215 nm and a low resonance electrospray mode (ESI).

Additional Intermediates Used to Prepare Compounds of the Invention Intermediate DX: 1-(4-bromo-5-fluoro-2-methoxyphenyl)-2-oxo-1,2-dihydroquinoxaline-6-sulfonyl chloride

Step 1: 4-(benzylthio)-2-nitroaniline

A RBF was charged with 4-bromo-2-nitroaniline (21.698 g, 100 mmol), Xantphos (2.89 g, 5.00 mmol), tris(dibenzylideneacetone)dipalladium (0) (2.289 g, 2.500 mmol), 1,4-dioxane (100 ml), N,N-diisopropylethylamine (34.8 ml, 200 mmol), and benzyl mercaptan (12.42 ml, 105 mmol). The flask was fitted with a reflux condenser and lowered into an 80° C. heating bath. After 2 h, an additional portion of benzyl mercaptan (ca. 3 mL) was added After another 1 h, additional portions of Xantphos (1.45 g) and tris (dibenzylideneacetone)dipalladium (0) (1.15 g) were added. Finally, after an another hour, an additional portion of (12:15 pm). LCMS at 1 pm looked the same, so an additional portion of N,N-diisopropylethylamine (6 mL) was added. After 30 min, the mixture was diluted with water and extracted with EtOAc (3×). The combined organic extracts were dried over sodium sulfate and filtered through celite. The filtrate was concentrated. The mixture was taken up in DCM and filtered. The filtrate was concentrated. The residue was taken up in MeOH and filtered. The collected solid was washed with MeOH (2×), then dried under a stream of N₂ (g) for 1.5 h to give 10.97 g of an orange solid. The process was repeated with the filtrate to give an additional lot of product (2.84 g). The two materials were combined to give 4-(benzylthio)-2-nitroaniline (13.81 g, 53.1 mmol, 53.1% yield) as a rust-colored solid that was 90% pure by LCMS. m/z (ESI) 261.0 (M+H)⁺.

Step 2: N-(4-(benzylthio)-2-nitrophenyl)-4-bromo-5-fluoro-2-methoxyaniline

A RBF was charged with 4-(benzylthio)-2-nitroaniline (13.72 g, 47.4 mmol), 1-bromo-2-fluoro-4-iodo-5-methoxybenzene (17.27 g, 52.2 mmol), Xantphos (1.372 g, 2.372 mmol), Pd₂(dba)₃ (1.086 g, 1.186 mmol), CPME (95 ml) and cesium carbonate (23.18 g, 71.2 mmol) were added. A reflux condenser was attached and the flask was lowered into a 90° C. heating bath. The mixture was stirred overnight. In the morning, the solid was scraped of the bottom of the flask, and an additional portion of cesium carbonate (23.18 g, 71.2 mmol) was added. The flask was returned to the heat with vigorous stirring for 3 h. After cooling, the mixture was diluted with EtOAc and filtered through celite with the aid of EtOAc. The filtrate was concentrated, and the residue was dissolved in DCM and loaded onto a pre-equilibrated 340-g SNAP Ultra column. The column was eluted with 0-30% EtOAc/Heptane. The material crashed out on the column, so the elution was changed to 0-50% EtOAc/Heptane with 10% DCM. The eluent was raised to 100% EtOAc, 20% DCM. Fractions containing product were combined and concentrated to give 22.96 g (>100% yield) of N-(4-(benzylthio)-2-nitrophenyl)-4-bromo-5-fluoro-2-methoxyaniline as a red solid that was 80-90% pure by LCMS. m/z (ESI) 563.0 (M+H)⁺.

Step 3: 4-(benzylthio)-N-1-(4-bromo-5-fluoro-2-methoxyphenyl)benzene-1,2-diamine

A 3-neck 500-mL RBF was fitted with a mechanical stirrer, a reflux condenser, and an additional funnel. Acetic acid (100 mL) was added, followed by iron (31.4 g, 563 mmol). The flask was heated for 10 min in a 60° C. oil bath. Then a solution of N-(4-(benzylthio)-2-nitrophenyl)-4-bromo-5-fluoro-2-methoxyaniline (21.726 g, 37.5 mmol) in THF (75 mL) was added via the addition funnel over 25 min, and the addition funnel was washed with THF (2×). The mixture was cooled for 10 min, then filtered through celite. The filter cake was washed with THF (4×), then was removed from the filter and suspended in EtOAc. The suspension was filtered, and the filter cake was washed further with EtOAc (4×). All of the combined filtrates were concentrated. The material was dissolved in DCM (with a minimal amount of MeOH) and was loaded onto a 50-g SNAP Ultra column. The column was partially dried under vacuum then was eluted onto a pre-equilibrated 340-g SNAP Ultra column with 10-30% of a 3:1 EtOAc/EtOH mixture in heptane with 10% of DCM as co-eluent. Several mixed fractions were discarded, and the remainder containing product were combined and concentrated to give 4-(benzylthio)-N-1-(4-bromo-5-fluoro-2-methoxyphenyl)benzene-1,2-diamine (13.49 g, 31.1 mmol, 83% yield) as a brown foam. ¹H NMR (400 MHz, DMSO-d₆) δ=7.40-7.17 (m, 5H), 7.08 (d, J=6.5 Hz, 1H), 6.89 (s, 2H), 6.80-6.73 (m, 1H), 6.59-6.50 (m, 1H), 6.17-6.08 (m, 1H), 4.98-4.76 (m, 2H), 4.14 (s, 2H), 3.84 (s, 3H). m/z (ESI) 433.0 (M+H)⁺.

The flask was flushed with Ar (g), then DMF (2526 μl) and ethyl bromoacetate (168 μl, 1.516 mmol) were added in sequence. The flask was heated to 50° C. for 6 h. The mixture was diluted with water and extracted with EtOAc (2×). The combined organic extracts were dried over sodium sulfate, filtered, and concentrated. The residue was taken up in DCE (5 mL) and trifluoroacetic acid (973 μl, 12.63 mmol). The flask was fitted with an air-cooled reflux condenser and heated to 50° C. overnight. The mixture was concentrated, and the residue was taken up in DCE (2.5 mL). Manganese dioxide (165 mg, 1.895 mmol) was added in one portion After 5 min, more DCE (2.5 mL) was added because the mixture was fairly thick. Following 30 min of stirring, the mixture was diluted with a small amount of DCM and filtered through celite with the aid of DCM. The filtrate was concentrated. The residue was taken up in DCM and loaded onto a 5-g silica gel loading column.

Biological Assays

The following assays were used in testing the exemplary compounds of the invention. Data for those examples tested in accordance with the procedures described below are presented in Table 1 herein.

Nav 1.7 or Nav 1.5 IWQ In Vitro Assay

HEK 293 Cells stably transfected with either Nav 1.7 or Nav 1.5 were recorded in population patch-clamp mode with the IonWorks® Quattro automated electrophysiology system in accordance with the manufacturer's specifications (Molecular Devices, LLC, Sunnyvale, Calif.). Sodium channel currents were measured in response to a train of depolarizations that induced successively greater inactivation.

Cells were held at −110 mV for three seconds (Nav 1.7) or half a second (Nay 1.5) from a holding voltage of −15 mV, then put through a series of 26 pulses of 150 msec duration to −20 mV at a frequency of 5 Hz. Cells were then left unclamped for a period of 3 to 8 minutes while a single concentration of test compound was added. Cells were then reclamped and put through the same voltage protocol. Current at the end of the 26^(th) pulse to −20 mV was subtracted from the peak current evoked by the 26^(th) pulse to −20 mV to correct for leak current. Percent block was calculated for each concentration in duplicate, and IC₅₀ curves were fitted to percent block as a function of concentration.

Nav 1.7 In Vitro PX Assay

HEK 293 cells stably transfected with human Nav1.7 were recorded in whole cell voltage clamp mode with the PatchXpress automated electrophysiology system (Molecular Devices, LLC, Sunnyvale, Calif.). Compound effects were measured on a partially inactivated state of the sodium channel. Cells were clamped to a holding potential yielding 20 to 50% inactivation. To elicit sodium current, channels were activated by pulsing to −10 mV for 20 msec. This voltage protocol was repeated at a rate of 0.1 Hz throughout the experiment. A single concentration of test compound was applied to cells for a duration of 3 minutes. Peak sodium current was measured at the end of the compound addition period to determine percent inhibition. Three to five cells were tested per concentration, and IC₅₀ curves were fitted to percent inhibition as a function of concentration. Data for compounds representative of the invention are presented in the Tables herein.

Nav 1.5 In Vitro PX Assay

293 cells stably transfected with Nav 1.5 were recorded in whole cell voltage clamp mode with the PatchXpress automated electrophysiology system according the manufacturer's specifications (Molecular Devices, LLC, Sunnyvale, Calif.). Cells were held at a holding potential of −50 mV to inactivate sodium channels. To elicit sodium currents the voltage was changed to −120 mV to recover a portion of the channels, followed by delivery of test pulses of 20 msec duration to 0 mV, at 0.1 Hz. A single concentration of test compound was applied to cells for a duration of 5 minutes. Peak sodium current was measured at the end of the compound addition period to determine percent inhibition. A minimum of two cells were tested per concentration. IC₅₀ curves were fitted to percent inhibition as a function of concentration. Data for compounds representative of the invention are presented in the Tables herein.

The compounds of the present invention may also be tested in the following in vivo assays.

Rat Formalin Model of Persistent Pain

On the test day, animals (Naïve, male Sprague Dawley rats) weighing between 260-300 g at the start of testing can be obtained from Harlan (Indianapolis, Ind.). All animals may be housed under a 12/12 h light/dark cycle with lights on at 0600. Rodents can be housed two to a cage on solid bottom cages with corn cob bedding and can have access to food and water ad libitum. Animals should be allowed to habituate to the vivarium for at least five days before testing is begun and should be brought into the testing room at least 30 minutes prior to dosing. Animals are pretreated with the appropriate test compound either by oral gavage or intraperitoneal injection at the desired pretreatment time (typically two hours before test onset) and then returned to their home cages. After dosing and at least 30 minutes prior to test onset, animals can be acclimated to the individual testing chambers. At test time, each animal can be gently wrapped in a towel with the left hindpaw exposed. A dilute solution of formalin (2.5%) in phosphate buffered saline can be injected subcutaneously into the dorsal surface of the left hindpaw in a volume to 50 μL with a 30 g needle. Immediately following injection, a small metal band can be affixed to the plantar side of the left hindpaw with a drop of LOCTITE (adhesive). Animals may be then placed into the testing chambers and the number of flinches can be recorded between 10 to 40 minutes after formalin injection. A flinch is defined as a quick and spontaneous movement of the injected hindpaw not associated with ambulation. Flinches can be quantified with the aid of the Automated Nociception Analyzer built by the University of California, San Diego Department of Anesthesiology. Individual data can be expressed as a % maximal potential effect (% MPE) calculated with the following formula: (−(Individual score−Vehicle average score)/Vehicle average score))*100=% MPE

Statistical analysis can be performed by analysis of variance (ANOVA), with post-hoc analysis using Bonferroni compared to the vehicle group for a significant main effect. Data can be represented as mean % MPE+/−standard error for each group.

Rat Open Field Assay

On the test day, animals (Naïve, male Sprague Dawley rats) weighing between 260-300 g at the start of testing may be obtained from Harlan (Indianapolis, Ind.). All animals can be housed under a 12/12 h light/dark cycle with lights on at 0600. Rodents can be housed two to a cage on solid bottom cages with corn cob bedding and can have access to food and water ad libitum. Animals should be allowed to habituate to the vivarium for at least five days before testing is begun and should be brought into the testing room at least 30 minutes prior to dosing. In a room separate from the testing room, animals can be pretreated with the appropriate test compound either by oral gavage or intraperitoneal injection at the desired pretreatment time (typically two hours before test onset) and then can be returned to their home cages until the pretreatment has elapsed. At test time, animal can be transferred to the open field testing room in their home cages. Each animal may be placed in a separate testing chamber and the motion tracking system is started. The house lights in the testing room should be turned off and the animals can be allowed to explore the novel open field for 30 minutes. An automated motion tracker, made by San Diego Instruments, San Diego, Calif., can be used to capture animal exploration with the aid of infrared photo beams to detect animal movement. These behaviors include basic movement and vertical rearing, which can be used as the primary endpoints for this assay. At the end of the test, house lights can be turned on and the animals should be removed from the testing apparatus. Data can be expressed as a percent change from the vehicle control using the following equation. (1−(Test mean/Vehicle mean))*100=% Change.

Statistical analysis can be performed by analysis of variance (ANOVA), with post-hoc analysis using Dunnett to follow up significant main effects.

Mouse Formalin Model of Persistent Pain

Mice (Naïve, male C57B1/6) weighing between 22-30 g at the start of testing were obtained from Harlan (Indianapolis, Ind.). All animals were housed under a 12/12 h light/dark cycle with lights on at 0630. Rodents were singly housed on solid bottom cages with corn cob bedding and had access to food and water ad libitum. Animals were allowed to habituate to the vivarium for at least five days before testing was begun and were brought into the testing room at least 30 minutes prior to dosing. Animals were pretreated with the appropriate test compound either by oral gavage or intraperitoneal injection at the desired pretreatment time (typically two hours before test onset) and then returned to their home cages. After dosing and at least 5 minutes prior to test onset, animals were acclimated to the individual testing chambers. At test time, each animal was gently wrapped in a cloth glove with the left hind paw exposed. A dilute solution of formalin (2%) in phosphate buffered saline was injected subcutaneously into the dorsal surface of the left hind paw in a volume to 20 μL with a 30 g needle. Animals were then placed into the observation chambers and the behaviors were recorded for 60 minutes following the formalin injection. A pain-like behavior was defined as licking and/or non-weight bearing of the injected hind paw not associated with ambulation.

Statistical analysis was performed by analysis of variance (ANOVA), with post-hoc analysis using the Dunnett post-hoc test compared to the vehicle group for any significant main effect. Data were represented as mean+/−standard error for each group.

Mouse Open Field Assay

Mice (Naïve, male C57BI/6) weighing between 22-30 g at the start of testing were obtained from Harlan (Indianapolis, Ind.). All animals were housed under a 12/12 h light/dark cycle with lights on at 0630. Rodents were singly housed on solid bottom cages with corn cob bedding and had access to food and water ad libitum. Animals were allowed to habituate to the vivarium for at least five days before testing was begun and were brought into the testing room at least 30 minutes prior to dosing. In a room separate from the testing room, animals were pretreated with the appropriate test compound either by oral gavage or intraperitoneal injection at the desired pretreatment time (typically two hours before test onset) and then returned to their home cages until the pretreatment has elapsed. At test time, animal were transferred to the open field testing room in their home cages. Each animal was placed in a separate testing chamber and the motion tracking system was started. The house lights in the testing room were turned off and the animals were allowed to explore the novel open field for 30 minutes. An automated motion tracker, made by Kinder Scientific, Poway, Calif., was used to capture animal exploration with the aid of infrared photo beams to detect animal movement. These behaviors include basic movement and vertical rearing, which were used as the primary endpoints for this assay. At the end of the test, house lights were turned on and the animals were removed from the testing apparatus.

Statistical analysis was performed by analysis of variance (ANOVA), with post-hoc analysis using the Dunnett post-hoc test compared to the vehicle group for any significant main effect. Data were represented as mean+/−standard error for each group. Data was also expressed as a percent change from the vehicle control using the following equation: (1−(Test mean/Vehicle mean))*100=% Change. CFA-Thermal Assay

Animals (Naïve, male Sprague Dawley rats) weighing between 260-300 g at the start of testing) can be obtained from Harlan (Indianapolis, Ind.). All animals can be housed under a 12/12 h light/dark cycle with lights on at 0600. Rodents may be housed two to a cage on solid bottom cages with corn cob bedding with access to food and water ad libitum. Animals can be allowed to habituate to the vivarium for at least five days before testing was begun and may be brought into the testing room at least 30 minutes prior to dosing. The Complete Freund's Adjuvant (CFA)-thermal assay may use a three continuous day testing schedule consisting of a habituation day, a baseline day, and a test day. On day 1, animals can be brought into the testing room, labeled, and placed in their individual testing boxes on the testing apparatus. Animals may be allowed to explore this environment for at least an hour without actually being tested. After habituating, animals can be placed back in their home cages and returned to the vivarium. On day 2, animals can be brought back into the testing room and placed on the testing apparatus and allowed to calm down (typically 30-45 minutes). A basal thermal threshold should be then taken with the following procedure: once calm, a Ugo Basile plantar device is placed under the animals left hindpaw; the start button is depressed turning on a steadily increasing thermal source and a timer; when the animal reaches its thermal threshold it will flinch its hindpaw, stopping the timer and the thermal stimulus. This latency to flinch can be recorded three times for each animal, with at least 5 minutes between trials, and the mean score can be used as the animal's baseline threshold. After testing, animals can be injected intraplantarly with a 25 μg/50 μl of complete Freund's adjuvant into the left hindpaw. Animals are then retuned to their home cages and returned to the vivarium. On test day, animals can be again placed on the thermal testing apparatus and their post-CFA baselines obtained with the procedure outlined above. Animals can be pretreated with the appropriate test compound either by oral gavage or intraperitoneal injection at the desired pretreatment time (typically two hours before test onset) and then can be returned to their home cages. Thirty minutes prior to testing, animals can be placed on the apparatus again. Once the pretreatment time has elapsed, animals can be again tested with the procedure above. Data may be expressed as a percent maximal potential effect with the following formula: ((Post-Drug Mean−Pre-Drug Mean)/(Baseline Mean−Pre-Drug Mean))*100=% MPE

Statistical analysis can be performed by analysis of variance (ANOVA), with post-hoc analysis using Bonferroni compared to the vehicle group for a significant main effect. Data can be represented as mean % MPE+/−standard error for each group.

Spinal Nerve Ligation (Chung)

Animals (Naïve, male Sprague Dawley rats) weighing between 150-200 g at the start of first time testing can be obtained from Harlan (Indianapolis, Ind.). All animals may be housed under a 12/12 h light/dark cycle with lights on at 0600. Rodents can be housed two to a cage on solid bottom cages with corn cob bedding with access to food and water ad libitum. Animals may be allowed to habituate to the vivarium for at least five days before testing is begun. Surgery may be then performed based on the method described by Kim and Chung (1992). Briefly, animals can be placed under isoflurane anesthesia and placed in a sterile surgical field. The area of the lumbar spine is excised and the spinal nerves at L4-L5 are exposed. The L5 spinal nerve is identified and tightly ligated with 5-0 silk suture. The muscle may be closed with absorbable suture and the skin with wound clip. Animals may be returned to the vivarium for 7-14 days and monitored daily. On test day, animals can be brought into the testing room and placed on a wire mesh floor in individual testing chambers. They may be allowed to acclimate to the chambers until they are calm. A series of Semmes-Weinstein monofilaments (von Frey hairs) with calibrated bending forces are then applied to determine a hyperalgesic baseline following the method set forth by Chaplan et al. (1994). Briefly, filaments are applied with an increasing force (if there was not reaction to the previous stimulus) or decreasing force (if there was a reaction to the previous stimulus) until a baseline value is reached. Animals are then pretreited with the appropriate test compound either by oral gavage or intraperitoneal injection at the desired pretreatment time (typically two hours before test onset) and then returned to their home cages. Thirty minutes prior to testing, animals are placed on the apparatus again. After the pretreatment time had elapsed, the procedure above is repeated to determine drug efficacy. Data can be expressed as the mean gram force to elicit a nociceptive behavior. Statistical analysis can be performed by analysis of variance (ANOVA), with post-hoc analysis using Bonferroni compared to the vehicle group for a significant main effect.
